"Port Support Zone Act of 2015."

This bill establishes a "Port Support Zone" within a five-mile radius of the Port Newark-Elizabeth Port Authority Marine Terminal to prepare for increased shipping volume following the Panama Canal expansion. It allows overweight commercial vehicles (80,000+ lbs) to operate on designated routes within commercial/industrial zones of the zone via special permits, while prohibiting zoning changes that would alter commercial/industrial classifications there. The bill also increases redevelopment grant funding for projects in the zone (up to 40% of project costs, with higher limits for environmental remediation) and prioritizes cleanup of contaminated sites for warehouse/distribution use supporting port operations. These provisions aim to streamline cargo movement, storage, and infrastructure development in the port area.
